# Responsibly Abandoning Open Source Projects - Jason Turner - NDC Copenhagen 2026

**[NDC Conferences](https://daily.dev/sources/ndc)** · 58 min read · 0 upvotes · 0 comments

## Summary

Jason Turner's NDC Copenhagen 2026 talk covers how to responsibly wind down an open source project so it reads as 'complete' rather than 'abandoned'. He argues the real issue is accountability — users distrust unmaintained projects because there's no one to blame if something breaks. The talk walks through best practices for proving code quality before stepping away: aggressive static analysis (linting, type checking), layered test coverage (line, branch, path), runtime analysis (sanitizers, Valgrind), fuzz testing, and mutation testing. For the handoff phase, he recommends paring tools down to industry standards to reduce friction for future contributors, automating CI on every PR, triaging all open issues, and avoiding GitHub's 'archived' label unless a clear successor fork exists. He also shares how he used an AI agent (LeftBot) to help resurrect ChaiScript by automatically opening pull requests for long-standing feature requests.
